【Abstract】 The application design and integration of MEMS ADXL02 based on MEMS were discussed. Firstly, the testing principles and important parameters designing rules were introduced. Then, a kind of wireless acceleration sensor based on ADXL202 was developed and acceleration was tested. The experimental result indicates that, MEMS ADXL202 is fit for monitoring the civil engineering structures whose signal is of low amplitude and changing slowly in frequency domain; the wireless acceleration sensor based on ADXL202 could be easily assembled and be applied compatibly to civil engineering structure monitoring.更多还原
